You create a store, but potential buyers complain about your products and service. what action should a wise business owner take?

In this case, you would look at the problems of the products and service like is the product gone wrong or is there not enough people in the business to help the customers check out or if they need feedback or even need help. Maybe also look into getting a new brand of products and possibly different employees. Hope this helped :)
